Presentation Title
Development of a 3D Digital Map in Hong Kong

Abstract
To support the development of Hong Kong into a smart city, the Lands Department has started the production of a three-dimensional (3D) Digital Map. Compared with traditional two-dimensional maps, 3D digital maps provide more realistic and extensive digital map data to help with geospatial data analysis and applications. The 3D digital map can present Hong Kong's urban landscape in more detail. Map users can study the appearance of buildings from different angles, measure their dimensions and retrieve relevant geographical information.

The 3D digital map dataset includes the territory-wide full-fledged 3D visualisation map, the 3D indoor map of 1250 buildings and the territory-wide 3D pedestrian network. The datasets have been published for public use in phases since 2021.

The speaker will introduce the Lands Department’s 3D digital mapping project and share with the audience current progress and roadmap in developing 3D digital maps in Hong Kong.
